Now, let's discuss the methods to get SketchUp Pro for free:

Blender is an open-source, completely free 3D creation suite. It is highly powerful but has a steeper learning curve than SketchUp.

Many users do not actually need the heavy desktop features of the Pro version. Trimble offers a completely free, trimmed-down version that runs directly in your web browser. $0 permanently.

Blender does not use the "push-pull" method. It is polygon-based, like Maya or 3ds Max. SketchUp users often struggle with Blender’s right-click select and modal editing. However, there are excellent "SketchUp to Blender" workflows and free add-ons (like "Blender for Architecture") that add walls, doors, and windows.

SketchUp offers a 30-day free trial for SketchUp Pro. This allows you to try the software and explore its features without committing to a purchase. During the trial period, you'll have access to all the features of SketchUp Pro. However, once the trial period ends, you'll need to purchase a license to continue using the software.
